"The safety of our guests, performers and crew is our primary concern and the potential risk was too severe for Sunday to go ahead," they said.

"We are very sorry for the disappointment and disruption caused to everyone who was looking forward to the final day of the festival. We understand that people will have questions about refunds. We will be giving all our guests further information about this over the coming days."

However, festival goers were not impressed and flocked to social media to file all sort of complaints against what they said was poor organisation against the reality of British summer time:

People stressed the fact that although Y Not was muddy, Glastonbury 2016 was much worse and still went ahead:

One family complained on Facebook about health and safety concerns and "completely false advertising of the 'family camping area'":

We know you can't control the weather, but you can plan for it. There was no provision whatsoever. People were struggling to walk anywhere in the mud, so how did you expect families to cope? There were no walkways, no straw put down, really no consideration whatsoever. We were unable to get to the arena even once as it was impossible to get the pushchair there and it was unsafe to walk there with a baby.

Other people said exits and entrances were cut off, signs weren't clear and security was overall poor and minimal:

Fans said organisers failed to buy wood chippings and hay to stabilise tracks and soak up the mud after the first night of rain. Moreover, many tents were robbed:

Many tents robbed, rampaging underage drinkers, so many kids on drugs, designated family areas with no one to supervise who camps in them, disaster of a VIP area, no campsite security posts whatsoever, plenty of mud; the good squishy sticky deep stuff, changing all of the set times and moving acts around without sticking up a couple of signs to let anyone know. I could go on.

The managing director of the company Ground Control, which was running Y Not festival, told the BBC he was "gutted" at what happened and said they used 80 tonnes of wood chip to firm up soggy ground.

"We have meetings every six hours to discuss things like weather conditions and ground conditions. On Saturday night it became increasingly clear conditions were deteriorating and at midnight there was not one agency which felt it was safe to continue."
